Many game species rely on their sense of smell to detect the presence of odors that spell danger, such as human odor.

Because of this, if even the slightest hint of human odor is detected, deer or the similar game will often flee.

This instinctual means of survival naturally makes getting into range for a bow shot a rather difficult prospect.

To overcome this difficulty, various brands of commercial scent eliminator became available for purchases on the open market. One such brand was Scent Killer.

Since Scent Killer was one of the first production-grade scent eliminators on the market.

The brand name has also served as a generic title used by hunters for other products of the same intended use.

These varying scent eliminator sprays are utilized by hunters worldwide to minimize various forms of human odor, therefore allowing them to get closer to the game on a more consistent basis.

This is most commonly accomplished by breaking down forms of odor-causing bacteria in order to destroy foreign odor from the source.

Does Scent Killer Work?

The debate on whether or not scent eliminators work has raged on ever since products of this nature were first introduced.

In recent years, several independent studies have been conducted to test the effectiveness of such products and the results are astounding.

Several years ago, Mississippi State University conducted a study on human odor and how it was affected by scent eliminator products.

In the study’s initial findings, it was found that a human odor predominantly comes from 2 sources:

  • A mixture of hundreds of compounds that are the result of varying strains of bacteria which are present in our bodies and on our skin.
  • Compounds that are released through our skin and breath as a result of the body’s normal breakdown of molecules to produce energy.

During the study, 65 individuals were given T-shirts to wear. Part of the study group wore shirts that had been treated with scent eliminator.

The other portion was given untreated shirts.

After each participant had worn the T-shirts for a lengthy, but equal period of time, the shirts were tested for VOCs (volatile organic compounds), the collective name given to human odor inducing bacteria and molecules.

The results of the study indicated that the t-shirts treated with scent eliminator greatly reduced the prevalence of 29 compounds that are known to produce human odor.

These results stand as a testament to just how effective the scent killer can be when striving for success in the field.

  • 16oz. Water (Distilled)
  • ¼ Cup Baking Soda
  • 1.5 Oz. Unscented Shampoo

This particular recipe will make approximately 2 pints of scent killer.

However, if you choose to alter the batch size, adjust quantities as necessary, keeping all mixture ratios the same.

Additional Items To Gather:

The following are additional items that should be gathered in advance of beginning the process of making your homemade scent killer:

How To Make Homemade Scent Killer for Hunting:

When making your homemade scent killer, certain steps should be taken to experience the highest possible level of success.

Step #1: Wash All Containers And Utensils


Before any ingredients are introduced into your bowl, funnel, jug, or spray bottle, they are to be thoroughly cleaned with scent-free detergent.

The same applies to your stirring spoon and filter cloth. Typical scent-free body washes or detergents are suitable for this process.

This is to prevent your end product from being contaminated by any foreign odors or chemicals.

Step #2: Begin With Distilled Water

Add your 3% Peroxide in equal parts to the water that has already been poured into the mixing bowl.

Step #4: Add Unscented Shampoo

Unscented Shampoo

Add the designated ratio of unscented shampoo into your mixing bowl.

Remember, if the batch size is to be adjusted, it is imperative to adjust the quantity of shampoo as well.

Step #5: Add Baking Soda

Next, add your baking soda to the mixture as specified based upon your batch size.

At this point, it is expected to see foaming and frothing take place. This is the intended chemical-reaction commencing.

Step #6: Stir Thoroughly


Take your plastic stirring spoon and gently stir your mixture.

Stirring times will vary, but you will need to continue stirring until all of the baking soda is dissolved within the mixture.

Step #7: Let Mixture Stand

You will now let your mixture sit for approximately 24 hours. This is to allow the chemical-reaction to continue before bottling.

During this time period, lightly cover your bowl with a piece of wood or item of similar nature.

This is not to seal off the container, as the venting of gasses from the chemical-reaction is necessary.

You are only preventing insects or other foreign debris from entering the mixture. For this reason, an actual lid of any kind is not advised.

Step #8: Pour Into Jug

Pour Into Jug

After your mixture has been left to stand for 24 hours, you are ready to pour it into the jug that you have gathered.

  • First, take the jug and secure your cloth filtering material over the opening.
  • Next, secure it in place with a rubber band.
  • You will now slowly pour your mixture through the cloth, into your jug with the use of a funnel. The filter cloth will catch any impurities or undissolved baking soda.

Step #9: Let Mixture Stand For 1 Week

Time Hunts Wisely

You will now place the lid onto the jug. Thread the lid onto the jug no more than one turn.

The lid is not to be tightened, as you need to allow any remaining gas from the chemical-reaction to vent.

You will now store the jug in a room-temperature location that is void of any direct sunlight.

A closet is a well-suited location for the storage of the mixture during this time.

Step #10: Bottle For Use

Bottle For Use

Once your mixture has sat for one week, you are ready to bottle for use.

With the aid of your pre-chosen funnel, slowly pour your homemade scent killer into a pre-designated spray bottle.

At this time, your mixture will be ready for use in the field.

Store any remaining scent killer in a room-temperature location that experiences no direct sunlight.

This will prolong the effective life of the mixture.

Additives For Earth Scent Blend:

Earth Scent Blend

Some hunters choose to add certain ingredients to their scent killer to create an earth scent blend, much like some store-bought applications.

This can be a highly effective means of eliminating your human odor, while also utilizing a form of cover scent that will add an additional layer of protection from a game animal’s attentive nose.

This process is accomplished by adding the organic matter of varying types to your scent killer recipe to achieve the desired effect.

Any number of organic materials can be selected for use in the production of a homemade earth scent blend of scent killer.

Commonly used earth scent additives include:

  • Cedar Foliage
  • Pine Needles
  • Walnuts
  • Acorns

# Pro-Tip: When choosing additives for an earth scent blend of scent killer, it is important to be aware that certain ingredients have the potential to stain hunting clothing.

Ingredients such as walnuts are known to produce a dye-like substance when soaked for an extended time.

For this reason, it is advisable to spray hunting clothing where the possibility of light staining will be of no concern.

A handy trick to minimize this effect is to turn hunting clothing inside out before spraying.

This places any discoloration in an area that is not outwardly visible, while still effectively reducing scent.

How To Utilize Earth Scent Additives During Production:

How To Utilize Earth Scent Additives During Production

While creating a homemade earth scent blend of scent killer can easily be done, there are a couple of key points that should be followed to complete the process efficiently.

1. Prepare in advanced:

Any earthen matter that you choose to utilize when making your homemade scent killer should be gathered in advance of beginning the production process. 

However, this should be done no more than 24 hours before you are to begin, to ensure the freshness of all ingredients.
2. All additional ingredients should be:

  • Added after the initial blend has been allowed to sit for 24 hours.
  • Placed in a jug in advance of the 1-week stand time.

Add the chosen ingredients through the opening in the jug, directly into the mixture and allow it to stand as previously described.

Adding these ingredients before this point in the process will lead to much of their natural aroma being suppressed.
3. After 1 week:

Once the mixture has been allowed to stand for one week, it will be ready for placement into spray bottles.

In this case, you will strain the mixture through your cloth strainer an additional time.

As you will need to remove the organic matter from your solution before final bottling.

This will allow the additives’ earth scent to remain while eliminating any solid-state materials that could potentially clog a spray nozzle.

#Pro-Tip: When choosing organic material for your scent killer in order to produce an earth scent blend, utilize only those materials that are native to the area that you hunt.

Deer and other game animals are accustomed to the scents that they encounter on a daily basis.

Any foreign odor, even if organic in nature, will put the game on alert.

For example, if pine trees are not present on the properties that you hunt, pine needles would be a poor choice when creating an earth scent blend of scent killer.

The Value Of A Job Well Done:

Now that you know how to make homemade scent killer, you will be well on your way to being undetected by game, at a fraction of the cost of what many spend on store-bought offerings.

The true reward will be the satisfaction you gain toward a job well done. As always, feel free to comment or ask any questions.
